So I'd ask for being able to mark questions as duplicate of a closed question (which is closed because it is off topic / not constructive / not a real question / too localized) when they're nearly exact duplicates (only formatting changes, minor text changes).

Why mark a question destined for closure / deletion as a duplicate of anything?

@Oded I feel that the duplicate would be the right option. It shows that the user simply reasked his question and has not improved it etc...

To highlight such a thing, use a comment and link to the duplicate.

@Oded This is how I do it now. But it should be contained in the more highlighted close reason.

If it's the same user then you can close it... are they then different users? What are the questions?

In such case the newer question should just be deleted. No point leaving two exact copies of the same thing around. Closing something as duplicate means it's the same, but still using different wording or somehow different so useful to keep around in addition to the other post.

@ShaWizDowArd eventually there should be some checkbox Exact duplicate you can only check when the levenshtein distance is inferior to 5-10% of the post size or so; the only option to bypass the has-no-answers-check...

If a question is not constructive / not a real question, I would rather close it for one of those reasons, rather than closing it as duplicate of a not constructive / not a real question.

If you close a question as duplicate of a not constructive / not a real question, everybody who is voting to delete the duplicated question would get a confirmation dialog asking if the question needs to be deleted, since there is a question closed as its duplicate.

Since the duplicated question doesn't have any answer, it doesn't make sense to point users to the other question that has been already closed, and that will never get answers.
If you need to point the OP to the other closed question because there are some interesting comments, leave a comment with a link to the other question, and vote to close as not constructive / not a real question.
